摘要
通过仪器法和人体法分别对防晒化妆品进行测定。分析比较了2种方法结果,研究了仪器法采用不同基质材料以及人体法中各参数对实验过程及结果的影响。结果表明,采用仪器法测得的结果比人体法偏高,尤其是使用大量物理防晒剂的配方时;对于仪器法,采用PMMA板比采用3M transpore膜具有更良好的相对偏差;采用人体法时,受试者的ITA值及性别与未防护皮肤的最小红斑量密切相关,但是对SPF值的最终测定结果影响不大。综合考虑上述参数,有助于合理调整紫外线强度及照射时间,提高实验效率,减少受试者的紫外伤害。
Protection effects of sun block were tested by both instrumental method and human body test method. The influences of various matrix materials in instrumental methods and diverse parameters in body test on the final test results were studied anti compared. The experiments indicated that the results of instrumental method is higher than that of human body test method, specially for those samples containing a lot of physical sunscreen agent. PMMA plate is much better than 3M transpore membrane in terms of relative deviation of instrumental method. ITA value and gender of subjects are closely related to the minimum erythema dose （MED）, but these parameters have rather little meaning of test resuhs. Integration of above factors helps adjust appropriately the intensity and time of UV irradiation to improve the tesl efficiency and reduce damage of subjects under UV exposure.
